An adventure company that takes divers and tourists on glass-bottomed boat tours of a coral reef ecosystem has noticed changes i

Semmy [17]

As we get closer to the coral reef, there are going to be several things we notice. The first thing we notice will be the large number of coral that seem to have lost their color, turning bright white. In addition, if we are in Florida, we may see something called the stony coral tissue loss disease. This disease has been of great concern in recent years in Floridian waters. Looking at these two changes, we can see that both are from the impact of climate change. As the water warms, the stress on the coral reaches a high point and they start to bleach and become more susceptible to several diseases.

I hope I've helped! :)

The Genectic units called ________ are made of sugar, a(n) ________ Group, and a(n) ________ base.

NNADVOKAT [17]

Answer:

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

Which part of the cell theory do these results most support:

Vlad1618 [11]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\huge\textbf{Cell Theory}$

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

All organism are composed of one or more cells

The cell is the structural and functional unit of life
It is a de novo structure, that means it COULD arise from non living thing which was incorrect.

It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

$\huge\textbf{Question:}$

<u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
<u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
<u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path

These observations support the point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

How does Glucose get into the cell?

Alex_Xolod [135]

Glucose gets into the cells through a process called facilitated diffusion. This is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy supplies and so it is called passive transport. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from outside of the cell membrane and into the cell.

(a) glucose is important because it is the primary source of energy for the cell.

(b) Glucose is 6 - carbon monomer of starch. It is a sugar.

(c) Glucose is broken down to pyruvate through the process of glycolysis.
